IMPROVEMENT IN WINDING AND SETTING WATCHES.

Specification forming part of Letters Patent No. 135,559, dated February4, 1873.

To all whom it may concern:

Beit known that I, CHARLES E. JAGOT, of Chaux de Fonds, Switzerland,have invented an improvement in Winding and Setting \Vatches, of whichthe following is a specitication:

This invention is for winding and setting watches without opening theinner case, said case not having any spaces through which dust can enterthe works.

I make use of a gear-wheel within the inner case connected with a crossarm and plate that is upon the outside of the said inner case or cap,and this gear-wheel ordinarily is in gear with a wheel upon thearborot'the main spring, so that said spring can be wound at any time,without opening the inner case, by simply revolving the cross-arm andparts connected thereto. in order to set the hands I provide a pinionupon the arbor ot'the hands and mount the aforesaid wheel and arms sothat they can be moved transversely sufliciently to bring the teeth ofthe wheels together. A slide and catch hold the parts while the watch isbeing set, and when the outer case is shut there is a spring thatreturns the parts to a normal position.

In the drawing, Figure l is a view of the parts upon the inside of thecap of the watch. Fig. 2 is a section of about twice the actual size,and on the line :v .1; of Fig. 3 of the cap and gear-wheels in position;and Fig. 5 is an exterior view of the cap and winding-arms.

The case of the watch is made in the usual manner, with the back a.hinged to the rim or bezel b, and c is the cap-plate to which thewinding and setting mechanism is attached. The winding-arms e c areconnected at the middle to a wheel, 2', that is inside the cap 0, saidconnection passing through an opening in the cap, but this opening iscovered by the central portion or plate 6 between the arms 6 c. Thewheel a is upon the arbor ot' the main spring, and the teeth thereofgear into the teeth of the wheel z, so that the watch can be wound atany time by simply revolving the arms 0 e. The usual ratchet-wheel andholding'pawl are provided for the spring-barrel. Upon the arbor ot' thehands is a pinion, 0, and the teeth of the wheel i project below thesurface of said wheel, as shown, so that when alateral movement is givento the wheel 6 sufticient to bring the teeth of the wheel 1 into contactwith those of the wheel 0, the hands can be set. This movement iseii'ected by meansot'a slide, 8, within the cap 0 connected to the wheel1', and passing through the edge of the cap and forming a catch, so thatwhen the slide 8 is drawn outwardly by the thumb or finger-nail in thenotch tot said slide 8 the teeth ot'i will be brought into gear withthose of 0, and the parts be held in that position by the catch of theslide 8 in contact with the edge of the cap; but when the case of thewatch is closed or the slide 8 depressed, the catch-will be liberatedand the spring a will return the gear-wheel t and slide .9 to theirnormal positions, liberating the hands.

I claim as my invention- The wheel '2' connected with the arms 6 andprovided with the slide 8 within the cap 0, in combination with thegear-wheel it upon the arbor of the main-spring and the pinion 0 uponthe arbor of the hands, substantially as set forth.
